Got my first road bike last year and after much deliberation, finally went over to clip ins a few months ago. Got spd pedals and Specialized shoes and when I went out first time had really cold and sore feet - but as it was only 5c outside, I thought that was why. Went out this week - was warm this time - and got back with really numb toes again. Had been out in between but only for short rides of less than an hour and not much of a problem then. Any-one else suffered the same or know a solution?
